The iSWAB™-Microbiome-EL (iSWAB™-MB-EL) collection device consists of a collection device that is pre-filled with 800 μL of the iSWAB™-MB-EL non-toxic, stabilizing buffer and fitted with a proprietary insert. The insert is designed to optimize the release of specimens collected with swabs into the stabilizing buffer, creating a minimal footprint and allowing for swab-free transport of specimens. The iSWAB™-MB-EL collection device eliminates the costly and time-consuming RNA isolation step from diagnostic workflows.
The iSWAB™-Microbiome-EL collection device is intended for the stabilization and inactivation of human specimens suspected of containing an infectious disease. This Device can be used for the collection, transport, and storage of specimens at ambient temperature (15-30 °C) and allows for the transportation of samples without a swab. Specimens collected in the iSWAB™-Microbiome-EL collection device are suitable for use with marketed molecular diagnostic tests for infectious diseases without the need for an RNA extraction step.
Indication for Use (from IFU)
The iSWAB™-Microbiome-EL collection device is intended for the stabilization and inactivation of microbial, viral, fungal, and spore DNA and RNA from various sample types including nasal, oral, vaginal, and skin. This device can be used for the collection, transport, and storage of specimens at ambient temperature. Specimens collected in the iSWAB-Microbiome-EL collection device are suitable for use with marketed molecular diagnostic tests for infectious diseases.
Storage and Stability
Pre-collection: 15 months from date of manufacture between 15-30° C.
Transport temperature, post-collection: 15-30° C.
Sample stability and storage 15-30° C 28 days for nasal specimens and 33 days for saliva specimens.
If longer storage time is required, collected samples can be stored at -20 to -80° C.
During the height of the COVID-19 pandemic, viral testing became the most effective tool to help bring outbreaks and surges under control. However, this comprehensive testing effort resulted in huge supply chain pressures, especially for lab consumables such as swabs and viral extraction reagents. Mawi DNA Technologies developed a modified “Extraction-Less” version of the non-invasive iSWAB™ technology. The iSWAB™-Microbiome-EL is designed to eliminate the RNA extraction step in the molecular testing workflow, allowing laboratories to perform direct RT-PCR and RT-LAMP on individual and pooled samples, eliminating or reducing the possibility of human error during long extraction protocols and the cost of extraction reagents, while increasing testing throughput. Additionally, the ambient temperature stabilization capacity of iSWAB™-MB-EL maintains the integrity of samples in cases of shipping delays/long shipping times or lab backlogs. This reduces the chances of false negatives and the need for patient re-sampling. Mawi DNA Technologies is committed to the creation of innovative technologies for effective and safe sample collection accessible to any person around the globe.
